I had a discussion with two friends over this topic the other night and they argue/claim that in math you see bully teachers more so than in other academic subjects. I reminded them that they were basing their observations on a relatively small and anecdotal sample size, but it nevertheless piqued my curiosity. I myself have had a bully math teacher before. Basically, this is someone who exhibits several of the following traits: 1.) Is arrogant. 2.) Dislikes questions being asked. 3.) Give very short - if any - replies that are often not very helpful. 4.) Makes fun of or derides in some way those who are not very competent in the subject. 5.) Openly questions students' intelligence (esp. if they try and ask simplistic questions). My friends' claim was that this is just a very common thing to see in mathematics and so I'm wondering if there is any truth to this in others' experiences? Also, if this is a problem, then why does it seem so prevalent in math versus other subjects?
